Orca

Orca is a 1977 horror film directed by Michael Anderson and produced by Dino De Laurentiis, starring Richard Harris, Charlotte Rampling, and Will Sampson. It is based on Arthur Herzog's novel of the same name. The film was poorly received by critics and audiences alike due in part to its similarities to the film Jaws released two years prior. Upon release the film received only minor theatrical success, but in recent years the film has achieved a cult following among fans of the natural horror subgenre. ... more on Wikipedia
